2019 BMW 640i xDrive Gran Turismo Tires

The 2019 BMW 640i xDrive Gran Turismo uses 245/45R19, 245/40R20, 275/35R20, and 275/40R19 tire sizes. The 245-width sizes are front-position fitments tied to either the 19-inch or 20-inch setup, while the 275-width sizes are the corresponding wider rear fitments.

The important next step is confirming which wheel package is actually on the car. A 19-inch setup and a 20-inch staggered setup are not the same thing, and front and rear sizes should not be chosen by width alone. Check wheel diameter, tire position, and whether previous owners changed wheels before ordering replacements.

The 2019 BMW 640i xDrive Gran Turismo uses either 19-inch or 20-inch rims, depending on the configuration. The 245/45R19 and 275/40R19 sizes are for 19-inch wheels, while the 245/40R20 and 275/35R20 sizes are for 20-inch wheels.

Wheel diameter should be verified before anything else because the tire size must match it exactly. A 19-inch tire cannot be mounted on a 20-inch wheel, and the same is true in reverse. On this BMW, wheel position also matters, since the front and rear can use different widths even when the rim diameter matches.

This model has more than one tire size because it can be equipped with either a 19-inch setup or a 20-inch staggered arrangement, and the rear tires are wider than the fronts. That creates separate front and rear fitments instead of one universal size for all four corners.

That means tire replacement should start with the actual wheel and axle position rather than the model name alone. A front tire and rear tire may share similar overall proportions while still using different widths and wheel diameters. Looking at the current wheel package on the vehicle avoids mixing a front fitment into a rear application or vice versa.

Start with the exact tire size and wheel position, since this BMW can use either a 19-inch setup or a 20-inch staggered front-and-rear combination. All of the available choices are radial tires, so the selection usually comes down to matching the correct size first and then comparing brand, series, sidewall style, and wheel compatibility.

After size, think about how the car is used and how you want it to look. Blackwall choices are available across the fitments, while some 20-inch options add raised white letter or redline styling. Rim-width range, load figures where shown, and the current wheel package on the car are all worth reviewing before narrowing the field.

Blackwall is the most widely available sidewall style for the 2019 BMW 640i xDrive Gran Turismo, and it appears across all covered sizes. In the 20-inch fitments, Pro-Trac Street Pro III options also add raised white letter and redline sidewall treatments for buyers who want a more distinctive presentation.

The sidewall choice does not change the need to match the correct front or rear size. On a modern grand-touring BMW, blackwall keeps the look closest to contemporary factory-era appearance, while raised white letter or redline can create a more customized look. It makes sense to choose appearance after the wheel diameter and position have been confirmed.

BFGoodrich, Nitto, and Pro-Trac offer tires for the 2019 BMW 640i xDrive Gran Turismo within the sizes covered here. Depending on the exact size, available series include g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.

Brand choice should come after the fitment basics are settled. Some sizes have only blackwall options, while certain 20-inch sizes also include raised white letter and redline alternatives. Comparing tire series, rim-width guidance where shown, and wheel position helps narrow the choices more effectively than choosing by brand name alone.

A period-style approach for a 2019 BMW 640i xDrive Gran Turismo usually starts with keeping the correct radial size and wheel-package relationship rather than changing the visual theme dramatically. Blackwall tires are available across all covered sizes and generally align best with the car’s original-era touring and performance character.

The main appearance decision comes after confirming whether the car is on 19-inch wheels or the staggered 20-inch setup. A blackwall presentation stays closest to the model’s contemporary look, while raised white letter or redline 20-inch options create a more personalized result. Exact originality matters more with wheel package and sizing than with cosmetic sidewall treatment alone.

On the 2019 BMW 640i xDrive Gran Turismo, tire construction does not create a bias-ply versus radial appearance decision because the primary fitments are radial. The visible appearance difference is more likely to come from sidewall style and tread presentation within the available radial tire families.

That keeps the focus on selecting the correct size and wheel package first, then choosing the look you want. Blackwall keeps the appearance more restrained and modern, while raised white letter and redline options in some 20-inch sizes add visual emphasis. For a restoration-minded result, matching the car’s wheel setup and overall character matters more than chasing novelty.

Yes. Wheel changes, suspension lowering, altered offsets, or body modifications can all affect tire fitment on a 2019 BMW 640i xDrive Gran Turismo, even when the tire size looks close to the original setup. That matters even more on staggered combinations, where front and rear widths already differ by design.

A car with aftermarket wheels should be checked for actual wheel diameter and width before replacement tires are chosen. Clearance at the strut, inner fender, and outer fender edge deserves attention as well, especially at full steering lock or full suspension movement. Using the original size code alone is not enough if the wheel and suspension setup has changed.

Before road use, inspect the wheel condition, verify that each tire matches its correct front or rear position, and make sure inflation is set appropriately for the application. It is also smart to look over valve stems, wheel balance, and the overall condition of the suspension and alignment hardware.

A quick clearance check can prevent problems, particularly on a staggered setup or on a car that may have seen wheel changes. Turn the steering from lock to lock, look for any rubbing marks, and confirm there is no contact under load. Recheck pressure and visual condition after the first drive so any issue is caught early.

Tires on a 2019 BMW 640i xDrive Gran Turismo should be inspected regularly, not just at service intervals. A visual check for uneven wear, cuts, sidewall damage, punctures, and air loss is worthwhile before longer drives, and a more careful inspection makes sense whenever handling, ride quality, or steering feel changes.

This is especially important on a staggered setup because front and rear tires do different jobs and may not wear the same way. Cars that sit for long periods should also be checked for aging, flat spotting, and pressure loss before returning to regular use. Routine inspection helps protect both fitment integrity and road manners.
